Onfido Ruby Library

The official Ruby library for integrating with the Onfido API.

Documentation can be found at https://documentation.onfido.com.

This version uses Onfido API v3.6. Refer to our API versioning guide for details of which client library versions use which versions of the API.

Installation & Usage

Installation

gem onfido, '~> 4.0.0'

Configure with your API token, region and optional timeout (default value is 30):

require onfido

Onfido.configure do |config|
  config.api_token = ENV["ONFIDO_API_TOKEN"]
  config.region = config.region[:EU]
  config.timeout = 30
end

onfido_api = Onfido::DefaultApi.new

All resources share the same interface when making API calls. Use .create to create a resource, .find to find one, and .all to fetch all resources.

Making a call to the API

applicant = onfido_api.create_applicant(
  first_name: 'Test',
  last_name: 'Applicant'
)

Documentation and code examples can be found at https://documentation.onfido.com

Error Handling

All errors are wrapped by ApiError coming from FaradayException:

• Connection timed out is raised in case of Faraday::TimeoutError
• Connection failed is raised in case of Faraday::ConnectionFailed

All errors provide the code, response_headers, and response_body of the error.

def create_applicant
  onfido_api.create_applicant(params)
rescue Onfido::ApiError => e
  e.message       # => 'Unprocessable entity'
  e.response_body # => { error: { type: "validation_error", message: "", fields: { "email": [ "invalid format" ] } } }
  e.code          # => '422'
end

Webhook event verification

Webhook events payload needs to be verified before it can be accessed. Library allows to easily decode the payload and verify its signature before returning it as an object for user convenience:

  require 'onfido/webhook_event_verifier'

  def webhook_verifier()
    verifier = Onfido::WebhookEventVerifier.new(ENV["ONFIDO_WEBHOOK_SECRET_TOKEN"])

    signature = "a0...760e"

    event = verifier.read_payload('{"payload":{"r...3"}}', signature)

  rescue Onfido::OnfidoInvalidSignatureError => e
    e.type
    e.fields
    e.response_code
  end

Contributing

This library is automatically generated using OpenAPI Generator (version: 7.9.0); therefore all the contributions, except tests files, should target Onfido OpenAPI specification repository instead of this repository.

For contributions to the tests instead, please follow the steps below:

1. Fork repository
2. Create your feature branch (git checkout -b my-new-feature)
3. Make your changes
4. Commit your changes (git commit -am 'Add some feature')
5. Push to the branch (git push origin my-new-feature)
6. Create a new Pull Request

Versioning policy

Semantic Versioning policy is used for library versioning, following guidelines and limitations below:

• MAJOR versions (x.0.0) might:
  • target a new API version
  • include non-backward compatible change
• MINOR versions (0.x.0) might:
  • add a new functionality, non-mandatory parameter or property
  • deprecate an old functionality
  • include non-backward compatible change to a functionality which is:
    • labelled as alpha or beta
    • completely broken and not usable
• PATCH version (0.0.x) might:
  • fix a bug
  • include backward compatible changes only
